The fan casing 2, is arranged down adjustment of the spout or trunk 12, an within vthe casing of the thrasher 1, ina proper adjusting cable 13, is connected at one end as position at the rear end thereof, to receive the at 14, to the outer upper end of said spout or straw and chaff that is passed through the trunk 12, and is guided through the cable roo 5o thrasher, and said obliquely disposed fau casguide 15, secured on toppof the thrasher 1, at ing 2, is provided with a top inlet opening the rear end thereof. The said cable guide 15, consists of an attachment plate 16, horizontal superimposed guide rollers 17 between which the cable passes, and a pair of parallel vertically disposed gilide rollers 18, supported at one side of the rollers 17, to receive the cable tllerebetween, so that the same may be easily adjusted, wllile at the saine time mov ing freely witll the lateral adj ustlnent of the conveyer spoilt or trunk as it automatically swings back and forth in a lateral direction, as will be more particularly referred to. From the cable guide 15, the cable 13, is guided to a suitably arranged winding drum 19, with whicll is connected the worm gearing 20, operated by a suitable hand wheel 21,at one side of the thrasller l, to provide for the up and down adjustment of the spout or trunk 12, on the hinge 1l.

The tubular conveyer spout or trunk 12, is provided at a point adjacent to the bottom hinge connection 11, with the neck 8, with a side hinge joint 22, that admits of the spout or trunk being folded directly against one side of the thrashing machine 1, wllen not in use,instead of being folded in an upright position or on top of the thrasher, as has beeny heretofore done in machines of this characier. The adjacent edges of the hinged sections of the spout directly opposite the side hinge joint 22, are provided with the bifurcated bolt lugs 223, to one of which is pivotally connected one end of a hinge bolt 24, the other end of which carries a thumb nllt 25, that is adapted to engage on the other bifurcated lug to provide for detachably connecting the hinged sections of the spout or trunk together, while at the same time allowing the long portion of the spout or trunk to be readily folded back against one side of the thrasher.

From `an intermediate point to the outer upper end thereof, the tubular conveyer spout or trunk 12, is provided with an open lower side 25h, that is formed by longitudinally bisecting the spout or trunk for a portion of its lellgtll, thereby leaving an outer arched end portion 25a disposed over the lower open side 25", and said lower open side 25h, of said arched end portion is adapted to be covered and ilncovered by a sliding seini-circlllar spout section 2G, working on and embracing the llnder side of said spoilt or trunk. The said semi-circularspont section 26, is provided at its opposite upper edges with the illtilrlled slide flanges 27, that loosely engage over the outwardly disposed ilpturned guide flanges 2S, formed at the opposite side edges ofthe arched end portion 25, of the said spout or trunk, and by reason of this connection the sliding spout section 26, may be adjusted to cover and uncover any portion of or the entire lower open side 25h, of the spout or trunk, according to the point Wllere it is desired todischarge the straw onto the stack. The sliding spoilt section 26 has connected thereto as at 29, the opposite ends of an adjusting chain 30, that is arranged to pass over the oppositely disposed wheels 31, mounted on one side of the spout or trunk l2, and to one of which is attached a suitable crank handle 32, to provide for adjusting the chain for sliding the spoilt section 2G, to the desired position.

A pair ot' curved supporting arms .'33, are rigidly connected at their inner ends as at 84, to opposite sides of the spout section 26, at the outer end thereof, and said curved supporting arms 23,project beyond the outer end of the spout section 2G, and are connected together by a transverse pivot rod 35, that is disposed to slide directly ilnder the semi-cil'- cular top portion 25, of the conveyer spout or trunk. The said transverse pivot rod 35, has pivotally mounted thereon a curved deilecting hood 3G, provided with an inner rounded end 37, that registers inside of the arched elld portion 25a, of the conveyer spout or trunk in order to provide for catching the straw or chaff and detlecting the salue down on to the stack directly as it passes beyond the outer eild of the spout section 2G. A spring 38, is coiled on the transverse pivot rod 35, and is connected at one end to the curved detlecting hood 3G, to provide for normally holding the inner rounded elld 37, i thereof within the top portion of the conveyer spout or trunk, and said inner rounded end 37,01. the dellecting hood is bent to forni a hook flange 38, that is adapted to be carried into engagement with a lloolc lug 39, fitted within the arched end portion 25, at the outer extremity thereof, so that when the spout lsection 2G, has been adjusted to entirely inclose ille outer lower open side of the colli veyer spout or trunk, the dellecting hood alld supporting arms therefor will be antoinatically elevated to a position disposed beyond the outer extremity of the spoilt or trunl; 12, to provide for the proper deflection of the straw on to the stack as will be readily ilnderstood.

The obliqnely disposed transversely oscillating fan casing 2, has attached to dialnetrically opposite sides thereof the opposite extlemities of an operating chain 40, alld at one of its attached extremities, vthe said cllain is connected with an adjusting screw4l, engaging ill a nut 42, at one side of the fan casing to provide for maintaining the said chain at a proper tension. Beyond the inner side of the obliqnely disposed fan casing 2, the chain 40, attached thereto, is arranged to pass over a chain wheel 43, lnounted on the upper end of a cllain operating shaft 44, journaled in a suitable bearing support 45, arranged in lollgitudinal alignment with the fan-shaft 4, that forms a pivotal support for the fan casing. The chaiil operating sllaft 44, has mounted j thereon intermediate of its ends a worin wheel 46, with which lneshes an adjacent wornl 47, arranged within a hoilsing or casing 4S, on the inner end of a worin operating shaft 49, the other end of which extends outside of the tllrasher l, and may be provided with a han'd wheel 50, for turniugthe same in order to provide for transversely or laterally oscillating ICO lof;

the fancasing to swing the conveyer spout or trunk back and forth over the stack, but the said worm shaft 49, has preferably mounted thereon the loose gear wheel 51. The loose gear wheel 51, is provided at one side with a clutch hub 52, adapted to be normally engaged by the spring actuated clutch collar 53, feathered on the shaft 49 and having connected thereto one end of the bell crank adjusting lever 54, that provides meansfor disengaging the clutch collar from the hub of the wheel l, when desired, and when the lever 54, is not adjusted, the wheel 51, is normally locked to the shaft 49, to provide for rotating the same. f

The gear wheel 5l, meshes with an adjacent pinion 55, loosely mounted on one end 't of a drive shaft 56, journaled transversely within the casing of the thrasher and carrying upon one end opposite the pinion 55the belt wheel or pulley 57. Theloosepinion 55, is provided at one side with a clutch hub 5S, that is adapted to be engaged by one end of a double clutch collar 59, feathered on the shaft 56, between the pinion 55, and a loose gear wheel 60, also mounted on the shaft 56, and provided at one slide with a clutch hub 6l, to be engaged by one end of the" collar 59. The loose gear wheel 60, meshes with an adjacent gear wheel 62, therebelow, and mounted on one end of a countershaft 63, mounted v insuitable bearings below the shaft 56, and

carrying on the end opposite the wheel 62, the pinion 64, meshing with the gear Wheel 5l, below the pinion 55, to provide for transmitting motion to the shaft 49, from thewheel 60, when the collar 59, is in engagement therewith.

The double clutch collar 59, is provided at a point intermediate of its ends with the an- ;nular groove 65, in which engages onevend of the clutch lever 66, the other end of which is pivotally mounted on the upper end of asupporting post 67, located adjacent to the rear side of the fan casing 2. The pivoted end of the clutch lever 66, is provided with the spaced lugs 68, between which plays a trip lever 69, the inner end of which is also pivotally secured on top ofthe pivoted end of the lever 66, on the upper end of the supporting post 67. The trip lever 69, has connected thereto at an intermediate point, as at 70, one end of a retractile spring 7l, the other end of which is connected to the upper end of a stationary attaching arm 72, arranged at a suitable point at one side and adjacent to the supporting v post 67.

The free end of the trip lever 69, is adapted to be engaged at either side by the spaced trip pins 73, that are adjustably fitted in any of a series of pin openings 74, in the casing liange 75, formed on the fan casing at the inner lower side thereof, and the distance between vthe spaced pins 73, regulates the swing or oscillation of the fan casing. Now it will be understood that when one of the pins 73, engages against one side of the trip lever 69,

the same will be moved against one of the lugs 68, of the clutch lever, and when the spring 71, has passed over the pivot of the trip lever, a continued pull will be exerted on the trip lever to cause the double clutch collar 59, to be thrown quickly into engagement with either of the clutch hubs 58, or 6l. A reverse adjustment of the clutch collar occurs when the trip lever is engaged by the other pin carried by the fan casing, and as the adjustment of the collar alternates between the pinion 55 and the wheel 60, the shaft 49, will be rotatedx alternately in opposite directions to provide 8o for imparting an oscillating movement to the fan casing 2, and therefore a lateral swing to the conveyer spout or trunk.

lChanges in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

`Having thus described the invention, what is claimed, and desired to be secured by Let- 9o conveyer spout or trunk hinged at its lower :on

end to the outer lower side of the casing neck and provided at a point adjacent to said hinge connection with the neck with a separate and independent side hinge joint that admits of a side folding of the spout or trunk independent of its inclination, a temporary fastening for the unhinged edges of the side hinge joint and means for raising and lowering the spout or trunk, substantially as set forth.
